Worked on enhancing the documentation for the pimcore/studio-backend-bundle repository, focusing on the Mercure cookie_same_site configuration to align with Symfony Cookie requirements. Addressed a documentation bug by clarifying that valid cookie_same_site values must be lowercase and explicitly listing 'lax', 'strict', and 'none' as acceptable options. Utilized Markdown to deliver precise, standards-compliant documentation, reducing the risk of runtime misconfigurations and supporting smoother developer onboarding. The update improved traceability by linking changes to a specific commit and issue, demonstrating attention to detail in documentation practices and a commitment to improving developer experience through clear, actionable technical writing.
